详细描述

Properties of type font default to the application's default font .

The most commonly used properties are:

• string font.family
• bool font.bold
• bool font.italic
• bool font.underline
• real font.pointSize
• int font.pixelSize

If both pointSize 和 pixelSize are specified, pixelSize 会被使用。

The following properties are also available:

• enumeration font.weight
• bool font.overline
• bool font.strikeout
• enumeration font.capitalization
• real font.letterSpacing
• real font.wordSpacing
• bool font.kerning
• bool font.preferShaping
• enumeration font.hintingPreference
• 对象 font.features
• string font.styleName
• 对象 [QML] {QtQuick::Text::}{font.variableAxes}

范例：

    Text {
        font.family: "Helvetica"
        font.pointSize: 13
        font.bold: true
    }
					

As font 是 structured value type, it can also be constructed with a JavaScript object:

    readonly property font myFont: ({
        family: "Helvetica",
        pointSize: 13,
        bold: true
    })
					

When integrating with C++, note that any QFont 值 passed into QML from C++ is automatically converted into a font value, and vice-versa.

This value type is provided by the QtQuick 导入。
